Monster Bloom by Grotek is the definitive tool for growers who aren't satisfied with average results and demand rock-hard, heavy flowers. This legendary powdered additive is specifically formulated to provide a massive injection of Phosphorus and Potassium right when your plants need it most to fatten up the crop.
You've spent months pampering your grow, controlling the climate, and watering with care, yet when the final weeks arrive, the flowers look airy, small, and lack that professional density. Does it sound familiar? You are looking for that "rock" effect, but you only get "popcorn" buds.
There is nothing more frustrating than putting in all the effort for a mediocre harvest that barely moves the scale. Watching your plants stall in the fattening phase feels like wasting time and electricity, leaving you wondering what the secret is to those magazine-quality crops.
The solution is simpler than you think: Monster Bloom. By introducing this high-concentration PK booster, you force the plant to focus all its energy on flower production and resin synthesis, turning those airy flowers into heavy, compact buds that will surprise you.
Using Monster Bloom in your feeding chart changes the rules of the game. Its main function is to maximize photosynthesis and starch production within the plant tissue. This translates directly into volume and weight.
It's not just about quantity; quality improves drastically. By providing the necessary levels of Phosphorus (50%) and Potassium (30%), you are giving the plant the raw material to create essential oils and terpenes. The result is a harvest that is not only heavier but also more aromatic and potent. It is the perfect complement to your base cannabis fertilizers.
This product is extremely concentrated, so "less is more." Using it correctly is key to avoiding over-fertilization and getting the most out of every gram of powder.
Because it is a powdered product, humidity is its worst enemy. Always keep the container tightly closed in a cool, dry place. If moisture gets in, it might cake up, making it harder to dose accurately.
Also, remember that Monster Bloom is powerful. If you see burnt tips on the leaves (nutrient burn), reduce the dose immediately. It is always better to start with a slightly lower dose and increase it as you see how your specific strain reacts.
You should start when the buds are already formed and the "fattening" phase begins, usually around week 4 or 5 of flowering, depending on the strain.
Yes, it is compatible with most base fertilizers. However, be careful if you use other PK boosters at the same time to avoid raising the EC too much.
Absolutely. Being a highly soluble mineral fertilizer, it does not clog drippers or ducts, making it ideal for hydro and aero systems.
If used correctly and flushed properly before harvesting and drying marijuana, it actually enhances the flavor by increasing resin production. If you don't flush, it might leave a metallic taste, so don't skip the final cleaning!
I've seen many trends come and go in this industry, but Grotek's Monster Bloom remains a fixture on my shelf for a reason: it works. I remember the first time I used it on a Critical crop; the difference in the hardness of the buds compared to the previous cycle was abysmal. It's like giving your plants a gym membership for the last month.
My personal trick is to be very careful with the dosage. Many people think that adding more powder will give bigger buds, but with Monster Bloom, the 0.3g/L limit is real. If you respect that and combine it with a good root flush at the end, the result is professional-grade weed: hard, heavy, and full of resin. It's a small investment for the weight you gain.

Hello, is this considered an organic product and do you think it would harm any beneficial microbe's in and organic soil mix? Like destany sooo gir example.
Works very well, you can see the difference with or without the fertilizer.
I have been using it for years and I won't change it, it's a very good product.
cuanta veces se usa 1 vez a ls semana o todos los dias
Very good flowering booster.
Flower booster, of very good quality, with remarkable results. Essential supplement during flowering! For me, the best!
Very good boost to use with caution on the dosage because in powder form, a small scale should be prepared to mix it, but results are visible quickly.
I already have the gh flora-series product line... is it safe to use?

The plant notices it shortly after starting to apply it, very recommendable quality-price.

Bonjour Kevin! I would leave it one more week to do a more complete root wash, since this fertilizer is not organic. Cordialement
